摘要

区域土壤侵蚀受到多种因素的影响和制约

在综合分析了影响福建省土壤侵蚀的主要因子:降水、地形起伏、土壤质地、植被因子和人为活动因子的基础上

根据国内外对土壤侵蚀敏感性评价的研究成果以及福建省的自然环境特征

确定了影响福建省土壤侵蚀的主要因子和敏感性等级。在GIS软件支持下

完成了评价指标数据的提取和集成

并按照敏感性等级标准进行土壤侵蚀敏感性评价。

Abstract

Regional soil erosion is limited by a number of factors

including precipitation

relief

soil quality

vegetation and human activity. With reference to domestic and international work on the assessment of sensitivity to soil erosion and to the natural environment characteristics of Fujian Province

the primary influences on and sensitivity grades of soil erosion are determined. GIS software is utilized to index resulting data and to extrapolate soil erosion sensitivity analysis.
